3. The device as claimed in claim 1 , wherein a paddle of the two or more paddles comprises a center region with a friction coating for contacting the item on the conveyor surface.

4. The device as claimed in claim 1 , wherein the first region includes a rigid region.

5. The device as claimed in claim 1 , wherein the second region is a flexible region which includes a brush.

6. The device as claimed in claim 1 , wherein the bi-directional sweeper belt includes a plastic belt positioned between a pair of rollers, wherein one of the rollers is a motorized drive roller.

7. The device as claimed in claim 1 , wherein a sprocket is attached to the pair of rollers and the bi-directional sweeper belt is looped around the pair of rollers.

8. A device for moving an item off of a conveyor surface comprising:

two or more paddles connected to a bi-directional sweeper belt, wherein the bi-directional sweeper belt is adjustably connected to a support frame, wherein the two or more paddles and the bi-directional sweeper belt form a paddle assembly positioned over the conveyor surface, and the paddle assembly comprises a first end and a second end each having drive rollers attached to sprockets to move the bi-directional sweeper belt;

at least one paddle bracket removably supported and fixed to an integrated element of the bi-directional sweeper belt, wherein the at least one paddle bracket connects at least one paddle of the two or more paddles to the bi-directional sweeper belt;

wherein at least one paddle of the two or more paddles comprises a brush that is configured to slide across the conveyor surface; and

wherein a first paddle of the two or more paddles is made of a different material than a second paddle of the two or more paddles.

9. The device as claimed in claim 8 , wherein one of the rollers attached to the sprocket is a motorized drive roller activated by a drive roller controller.

10. The device as claimed in claim 8 , wherein at least one of the rollers is attached to the sprocket via a welding flange and a sprocket toe clamp.

11. The device as claimed in claim 8 , wherein the paddle assembly comprises a compression spring as an automatic tensioning device to maintain tension on the bi-directional sweeper belt.

12. The device as claimed in claim 8 , further comprising a paddle link integrated into the bi-directional sweeper belt and attached to the at least one paddle bracket and the at least one paddle by one of a bolt, screw, rivet, or pin.

13. The device as claimed in claim 12 , wherein the at least one paddle comprises two paddle pieces connected by an adhesive to securely link the two paddle pieces with each other.

14. The device as claimed in claim 9 , wherein the motorized drive roller to control the movement of the bi-directional sweeper belt is capable of directing the two or more paddles to divert items from the conveyor surface toward either side of conveyor; and wherein the direction of movement of the motorized drive roller results in the left or right handed divert of the item from the conveyor surface when contacted by at least one of the two or more paddles.

15. The device as claimed in claim 8 , wherein at least one paddle of the two or more paddles comprises (a) a rigid top region for connecting to the bi-directional sweeper belt, (b) a center region with a friction coating for contacting the item on the conveyor surface, and (c) a flexible end region for positioning close to the conveyor surface.

16. The device as claimed in claim 8 , wherein the at least one paddle bracket connects the two or more paddles to the sweeper belt.

17. A device for moving an item off of a main conveyor surface comprising:

a paddle assembly connected to a sweeper belt, wherein the paddle assembly comprises a first paddle attached to the sweeper belt at a first location, and a second paddle attached to the sweeper belt at a second location;

wherein each of the first paddle and the second paddle is positioned to sweep over the conveyor surface to direct the item off the conveyor surface;

wherein the first and second paddles are made of different materials; and

wherein the first paddle comprises an attachment region for connecting to the sweeper belt, a center region to contact an article on the conveyor surface, and an end region positioned close to the conveyor surface.

18. The device as claimed in claim 17 , wherein the end region is adapted to contact the conveyor surface for sliding the item across the conveyor surface.

19. The device as claimed in claim 17 , further comprises: an electronic eye to sense a position of at least one paddle of the first and second paddles to determine if the sweeper belt has moved either left or right based on a known configuration of the other paddle in relation to the sensed position of the at least one paddle.

20. The device as claimed in claim 17 , wherein the paddle assembly is positioned at different distances from the conveyor surface when the paddle assembly is located above the conveyor surface by adjustably connecting the sweeper belt to a frame to allow positioning of end surfaces of the paddles.

21. The device as claimed in claim 17 , wherein the paddle assembly is configured to move with respect to the conveyor surface based on a likelihood of damaging the article, a size of the article, a type of article, a surface or packaging covering the article, or a speed of the main conveyor surface.

22. The device as claimed in claim 17 , wherein the sweeper belt is a continuous, part-circular sweeper belt, wherein each of the first paddle and the second paddle is removably connected to the sweeper belt by a rigid bracket that is fixed to an integrated element of the continuous, part-circular sweeper belt.

23. The device as claimed in claim 17 , further comprising a motorized drive roller activated by a drive roller controller to run forwards or backwards, and wherein the direction of movement of the motorized drive roller results in the left or right handed divert of the item from the conveyor surface when contacted by the paddles.
